This invention relatesto a per1omtor, and m0re particularly t0 0ne having spring pressed jaws, 0110 01 which lmving removably m0untecl there0n a perfomting 01 sl0tting ele1nent provided With cutting blacles a1- mngecl with respect t0 021011 0tl1er so tl1at tl1e sl0ts 01 perforations when f0rmed Will be spaced from each 0tl1er.

A still further 0bject 01 my invention is t0 provide simple ancl novel meztns adaptecl 101 use 101 fonning a plurality 01 sl0ts in a letter sheet 01 the like whereby in the transportati0n 01 stamps 01 simila1 Valuable articles they can be eflectively 001.1finecl between the portions 01 the letter sheet und a tongue 1'0rmed by my improvecl perforator.

Othe1 0bjects anal aclvantztges Will be apparent as the nature 01 the invention is bette1* set fortl1, ancl it Will be understoocl that clmnges within tl1e sc0pe 01 the claims may be resorted t0 without cleparting 110m the spirit 01 tl1e inxenti0n.

In the drawing, forming a ortion 01 this specification und in Wlii0h like characters 01 reference indicato similar parts in the several views:-Figure 1 is a perspective view 01 tl1e perforator. Fig. 2 is a side elevati0n 01' tl1e same. Fig. 3 is 0 vertical longitudinal seci0n. Fig. 1 is 0 detail vertical trm1sverse secti0n tln0ugl1 0110 01 the members 01 tl1e perf'0mtor. 1*ig. 5 is a perspective view 01 the perfomtor 01 sl0t forming element. Fig. 6 is 0 detail plan view 01 a piece 01 material showing the sl0ts f0rrned therein by my improved perfomtor ancl sh0wing tl1e manner 01 con1lning between tl1e tongue formed by the slot and portions 01 the material a stamp 01 like article.

Re1'01ring 110W n10r0 particularly t0 the drmving, there is sl10wn a pe1fomtor 00mp1ising members 1 and 2 piv0ted t0 00011 othe1 as sh0wn at 3, L11(l ns clem1yillustrated the 1nember 2 is providecl Witli an outwarclly extonding recluced porti0n 4 Wl1ich is slotted longitudinally at its oute1 end as at 5 so as t0 provide 0 yieldable t0ngue 6 which receives a removable perl'0mting 01 sl0t l'onning ele- 1nent 7 provided with parallel spaced blades 8 l1zwing beveled cutting edges 9.

element 7 is reduced in size at its outer end so 0s to provide a1; tl1e rear 01' said element p01nted end portions 10. The member 1 1s provided with a pair 01' spaced arms 11 be tween W111C11 the p01tion 4 01 tl1e lnember 2 1s adapted t0 m0ve and the latter is thus efiectively guidecl in an accurate 1nanner as Will be fully umlerstoocl. The member 1 is provicled w-ith a base plate 01 portion 12 Whi0h is spaced 110m the 2u1ns 11 to 1'011n a paper 1eceiving sl0t 13 101 a purpose t0 be hereina1'ter more 1'ully described. The base plate 01 portion 12 is provided with a pair 01' longitudinally extencling slots 14 Whi0h are disposed directly beneath the cutting blades 8 01' tl1e element 7. The members 1 and 2 are provided With handles 15 between which a, spring 16 is disposed, the tensi0n 01' the spring being t0 1'010e the handles 15 away 110n1 each 0tl1er normally so as t0 hold th0 blades 8 01' tl1e element 7 away 110111 the base plate 01 p01tion 12 in orcler that 1naterial 01 pape1 t0 be per1'0rated can be inserted in the slot 13 vritl1out any interruption.

In p1actice, when it is desirecl t0 pe11'010t0 a sheet 01' lette1 paper 01' t0 101m therein a plurality 01' spacecl slots, a porti0n 01' the letter sheet is passecl in the sl0t 13 and is tllus adapted t0 lie upon the base plate 01 p01ti0n 12 01' tl1e 1ne1nber 1. After thc pa p01has been pr0pexrly positioned, tl1e handles 15 1nay be 1nanipulated an (l 1orced manually t0warrd each 0ther, in W111C11 movement tl10 portion 4 01 ehe member 1 Will be 1noved downwarclly so that the blades 8 Will l'onn in the paper a pai1 01' longitudinal slots as illustratecl at 17 in Fig. 6 01' tl1e clrawing, providing a t0ngue 18 beneath which a. postage stzunp A 01 0the1 mticle t0 be transp01ted through tl1e 1nail can 130 passed anal securely held t0 the pstpe1 againstacci lental displacement 01 loss.
